This page describes how to use coreboot on the BCOM WinNET P680 motherboard. This board is used on the HP/Neoware e140 thin client.
This page is a work in progress.
This board works with target/bcom/winnetp680, except that it needs rev 3566 of src/southbridge/via/vt8237r.
- hda in Linux is hde in FILO
- loading kernel/initrd is very slow
- irq_tables.c from the factory BIOS does not work. The epia-cn table has been substituted, but it has problems too (Ethernet doesn't work right: 50% packet loss.). A workaround is to use the kernel parameter "irqpoll"
- Current code is broken (doesn't compile). Pull rev 3566 of src/southbridge/via/vt8237r
